Led grow lights grow plants during the vegetative stage very effectively however ever it can take a week or so longer before the plant fully enters the explosive vegetative growth stage, very short inter nodal lengths could sometimes be so short that side branches almost grow on top of each other. The plants can sometimes grow shorter and stouter although once flowering starts the plants still displayed the explosive growth associated with flowering.
Now the add some CFL bulbs into the mix and the growth pattern changes and growth rates explode, the first noticeable changes in the growth patterns are during vegetative when the growth levels increase some 200 - 300%. Plants are taller with more advanced side branching even after three weeks growth from seed compared to plants receiving only led light, the leaves are larger which enables the plant to harness more of the available light. The inter-nodal length increases slightly which allows improved airflow through the plant as well as allowing more light to penetrate down through the plant, all this allows more rapid growth above the ground so to speak however beneath the surface the improvements are even more noticeable.
Plants grown with both led grow lights and CFL bulbs exhibit more advanced root growth at a far earlier stage than those grown with either led grow lights on their own or CFL bulbs on their own, this rapid root growth allows for the plant to transport more nutrients to sustain the vigorous growth.
Now the flowering cycle is where the differences becomes even more apparent, the plant will be in the optimum condition with large leaves and a healthy root system ready to transport the nutrients needed to sustain healthy fruit and bud formation during the blooming phase. The CFL bulbs light work in harmony with the led grow light and fruits and buds grown under this combined light will be visibly larger and heavier. This combined light also increases the amount of bud/ fruit sites as well as more increased side branching and healthier stems, the CFL bulb also introduces a heat source into a led grow room which is always a welcome addition.
Excellent results have been achieved by growers using this combination of light sources and for those growing with led grow lights the simple addition of a few CFL bulbs can transform your plants into healthy monster plants.
For information on CFL and led grow lights the following company will be pleased to point you in the right direction - http://www.ledfusion.co.uk, although they specialise in led grow lighting they also promote energy efficient lighting so this is right up there street and they are an excellent source of both led grow lights and growing information.
